Abstract

The utility model discloses a kind of screws, including screw ontology, the screw ontology is integrally formed by three tail end, medial end portions and point parts, the tail end is located at one end of the medial end portions, the point is located at the other end of the medial end portions, and the tail end upper surface offers circular groove, is provided with hexagonal convex block at the circular groove center, the circular groove is internally located on the outside of hexagonal convex block and offers jack, and the medial end portions outer wall offers a slot.The outer diameter that the utility model is suitable for the tail end of the screw is identical as the outer diameter of medial end portions, tail end can also enter the inside of workpiece to the screw when in use in this way, on the one hand the aesthetics of outer surface of workpiece is improved, on the other hand after changing existing screw installation, tail end easily scratches the defect of user beyond workpiece surface.

Description

A kind of screw

Technical field

The utility model belongs to screw technical field, specially a kind of screw.

Background technique

Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages The tool of implements parts, screw are the general sayings of fastener, and daily pet phrase, screw is work indispensable in daily life Industry necessity: the minimum screw that such as camera, glasses, clock and watch, electronics use；TV, electric product, musical instrument, furniture etc. General screw；Large-scale screw, nut are then used as engineering, building, bridge；Traffic tool, aircraft, electric car, automobile etc. are then It is used in combination for big primary screw.Screw industrially bears vital task, as long as there is industry on the earth, the function of screw is eternal It is important；

The diameter of existing screw tail end is greater than the diameter of medial end portions, leads to screw so after mounting, tail end floats on The outside of workpiece is easy to scratch user, and existing screw can only be mounted and dismounted mostly by a kind of bottle opener, be caused Its use is not convenient enough, it is difficult to meet the needs of people.

Utility model content

The purpose of this utility model is that: in order to solve the problems in background technique, provide a kind of screw.

The technical solution adopted in the utility model is as follows:

A kind of screw, including screw ontology, the screw ontology is by three tail end, medial end portions and point part one Molding, the tail end are located at one end of the medial end portions, and the point is located at the other end of the medial end portions, the tail end Portion upper surface offers circular groove, and hexagonal convex block is provided at the circular groove center, and the circular groove is internally located at Jack is offered on the outside of hexagonal convex block, the medial end portions outer wall offers a slot.

Wherein, the outer diameter of the tail end is identical as the outer diameter of the medial end portions.

Wherein, the vertical spacing on the medial end portions the same face between two silk slots is twice of the silk groove width.

Wherein, hexagonal groove is offered at hexagonal convex block center.

Wherein, there are six the jack opens up altogether, and spacing is equal between any two for six jacks.

In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:

1, in the utility model, the outer diameter of the tail end of the screw and the outer diameter of medial end portions are identical, and the screw makes in this way Used time tail end can also enter the inside of workpiece, on the one hand improve the aesthetics of outer surface of workpiece, on the other hand change After existing screw installation, tail end easily scratches the defect of user beyond workpiece surface.

2, in the utility model, the tail end upper surface of the screw offers circular groove, is arranged at circular groove center There is hexagonal convex block, circular groove is internally located on the outside of hexagonal convex block and offers jack, and such structure setting makes the screw exist It can be mounted and dismounted by three kinds of different bottle openers when being mounted and dismounted, to improve screw peace installation and dismantling The convenience unloaded.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.

Referring to Fig.1-3, a kind of screw, including screw ontology 2, screw ontology 2 is by tail end 1, medial end portions 4 and point 5 Three parts are integrally formed, and tail end 1 is located at one end of medial end portions 4, and point 5 is located at the other end of medial end portions 4, tail end 1 Outer diameter it is identical as the outer diameter of medial end portions 4, in this way the screw when in use tail end 1 can also enter workpiece inside, a side Face improves the aesthetics of outer surface of workpiece, and after on the other hand changing existing screw installation, tail end is easily drawn beyond workpiece surface Hurt the defect of user, 1 upper surface of tail end offers circular groove 6, and circular groove is provided with hexagonal convex block 8 at 6 center, When being installed or removed to the screw, interior Hexagonal jacket driver sleeve can be rotatablely installed or be torn open on hexagonal convex block 8 It unloads, hexagonal convex block offers hexagonal groove 7 at 8 center, can be by by interior hexagonal when installing or removing to the screw Screwdriver is inserted in 7 inside of hexagonal groove and rotates and installed or removed；

Circular groove 6, which is internally located on the outside of hexagonal convex block 8, offers jack 9, and there are six jack 9 opens up altogether, and six are inserted Spacing is equal between any two in hole 9, when installing or removing to the screw, can be inserted into respectively by six special bottle openers Inside six jacks 9 and rotation is installed or removed；

4 outer wall of medial end portions offers a slot 3, and the vertical spacing on 4 the same face of medial end portions between two silk slots 3 is a slot 3 Twice of width, such structure can promote the intensity of a slot 3 He the screw silk wall, effectively prevent stripped thread phenomenon.

Working principle, referring to Fig.1-3, the outer diameter of the tail end 1 of the screw are identical as the outer diameter of medial end portions 4, in this way the spiral shell Tail end 1 can also enter the inside of workpiece to silk when in use, on the one hand improve the aesthetics of outer surface of workpiece, on the other hand After changing existing screw installation, tail end easily scratches the defect of user, 1 upper surface of tail end of the screw beyond workpiece surface Circular groove 6 is offered, hexagonal convex block 8 is provided at 6 center of circular groove, circular groove 6 is internally located at 8 outside of hexagonal convex block Jack 9 is offered, such structure setting allows the screw when being mounted and dismounted by three kinds of different bottle openers It is mounted and dismounted, to improve the convenience of screw installation and removal.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
